    Time is of the Essence

    Many of our biological processes follow a 24-hour ""body clock."" Triglyceride (TAG) levels do as well. Strangely, when no biological clock is present, TAG levels in mice still fluctuate. Dr. Gad Asher and colleagues changed when the mice ate – and cut their TAG levels in half. Could merely changing meal time treat TAG-related diseases?

  • Science Tips, July 2007

    Four research updates from the Weizmann Institute: doping electronics; experiments with interfering electrons; a new model of molecular recognition; and a promising cellular reporter.

    Lineage Trees Reveal Cells' Histories

    Using a method he developed for determining the ""family trees"" of cells, Prof. Ehud Shapiro and a cross-disciplinary team of Weizmann scientists, including Prof. Nava Dekel, was able to prove—and disprove—some ideas about the female mammal's egg supply.
